The document defines a simple sentence and its key elements. It discusses the syntactic features of 5 sentence elements - subject, verb, complement, object, and adverbial. It then examines the semantic roles that the subject, object, and complement can take, such as agentive, affected, recipient, and current/resulting attributive. Examples are provided to illustrate each concept. The document concludes with exercises asking the reader to identify semantic roles and generate sentences using current and resulting complements.
